Raveberry - First time grower, long time user

So_sa_do_si_do I might go overboard with the photos, not too sure yet. This is all still very new to me. I am still trying to remind myself not to freak out about every little thing.

So_sa_do_si_do This being my first grow, at this point I started wondering if I was not watering enough or too much. I was also still trying to figure out how to better hone in my humidifier.

So_sa_do_si_do Whelp figured out my PH meter was not reading correctly which means I was not balancing the PH of my water correctly....that being said I had been using RO water that *read* it was testing around 7.0, so I was using PH down to 6.5 5/27 - Decided to top the plant. Again with this being my first grow, this was slightly nerve-racking 5/28 - Seems I didn't mess up the top chop, woooh! I tested the PH of my soil today(5.6), if that even tells me anything(I find 2 articles that say it doesn't and another 2 that say the opposite...so that's magical) and ended up just buying a few gallons of distilled water from the store since I didn't want to be running my RO system for my plant and the others in my house.(made sense in my head at the time) Fed a dose of nutrients in the feeding tonight. I believe I was underwatering my plant. 5/29 Forgot to take a picture because I thought I might have overfed the nutes, on the night before.., So I spent the night researching info and trying to figure out if that was the case and how to correct it. But again since I am new to this, I have no clue lol. It also seems I had bumped up the light power from 50% to 100% some how the night before. Ended up dropping it down to 70% power. 5/30 I took the photo, then tied down the main stem. worries of overfeeding have subsided for now... 6/1 Looking extra bushy today. Holding off on defoliation, unless someone tells me otherwise. I am trying to hold off for a few days on doing anything more that could stress out my plant.
